Another trick is to take a blow torch around the center hub where the rotor meets it and where the lugs come throught the rotor as well. Works better with oxy acetylene, but a standard propane one will work just as well. You need to get it really hot and hammer on it while doing it.

Some factoy rotors have small tapped holes in the rotors that are meant for you to screw small "push" bolts into. These screws push against the back of the hub and force the rotors out and they pop off. You just need to make sure you know what bolt size to use and pick a couple up from Lowes, Home Depot, etc...

Slowly screw both of them in evenly and that will keep the rotors from trying to come off unevenly. If that happens they may bind up and be even more difficult to remove.

If your rotors do not have these small bolt holes drilled in them, you are looking at a battle. They will have to be pryed off, or beaten off with a hammer. Sometimes you may be able to get a steering wheel puller to fit on your rotors and use it to pry them off, but I bet you are looking at some banging.

No matter what, you will want to spray some penetrating lubricant onto the center hub where the rotor meets it and where the lugs come throught the rotor as well...this may ease the process.

I hope this helps a bit...I just went through the same process about 3 weeks ago...Good Luck!

On my 97" Suburban do

It depends. For a regular 1/2 ton and most 3/4 tons no, just remove the caliper and the rotor comes off over the wheel bearing hub. 1 ton suburbans, require more work, you will require a large socket to remove the axle nut, and a slide hammer or 3 jaw puller big enough to pull off the rotor and wheel bearing as an assembly. The rotor on some 3/4 tons and all 1 tons bolt from behind thru the wheel bearing and need to be removed together. The wheel bearing has to be unbolted from the spindle, then the wheel studs have to be punched thru to remove the rotor. The splines on the wheel studs hold the rotor to the wheel bearing. 1 ton will say 3500 on the side, 2500 for 3/4 ton and 1500 for 1/2 tons.

92 Camry New rotor, brakes Rotor still getting torn up by brakes.

You need to check for any looseness in the wheel that this is occuring, since you haven't mentioned which one. Did you tighten the axle nut enough? Is the caliper brake not twisted so as to not tighten when turning. The calper bracket may be out of line.

I have a 2003 lincoln navigator 4x4 and would like to know how to remove both front rotor

Remove the brake calipers and the caliper brackets. Then the rotors should slide off, (should) Some times you need to beat the hell out of them with a big hammer. But don't hit the wheel studs.
